  • Patent number: 6988800
    Abstract: A toric contact lens incorporating meniscus-shaped top and bottom flattened zones for dynamic stabilization comprises a convex outer surface and a concave inner surface. The lens has a central optic zone, a top meniscus-shaped flattened zone formed between upper edge of the optic zone and upper edge of the convex outer surface, and a bottom meniscus-shaped flattened zone between lower edge of the optic zone and lower edge of the convex outer surface, where a left intersection and a right intersection are formed by said top flattened zone intersecting said bottom flattened zone on both sides, which in turn form a plurality of horizontal positional lines each.
    Type: Grant

  • Patent number: 6939118
    Abstract: A molding apparatus for generating toric contact lenses, comprises a convex inserter, a front convex inserter carrier, a rear convex inserter carrier, and a first and a second fasteners. The convex inserter, used to form a convex outer surface of toric contact lens, has positioning lines on its convex head. It is embedded in the front convex inserter carrier which also has positioning lines on its upper brim, jointing with the convex inserter, and an angle pointing line on its cylindrical surface. A first fastener is used to helically tighten the convex inserter to the front convex inserter carrier while a second fastener joining the front convex inserter carrier with the rear convex inserter carrier. The front convex inserter carrier is embedded in the rear convex inserter carrier which has a number of lines representing angles of astigmatism on its cylindrical surface.
